Hi all,

I'm using Wildfly 9 to deploy two web applications (wars) simultaneously.  I recently upgraded the version of quartz used by one of the applications and now I'm getting the following error when I deploy:

Caused by: org.quartz.SchedulerConfigException: Unable to instantiate InstanceIdGenerator class: org.quartz.simpl.SimpleInstanceIdGenerator cannot be cast to org.quartz.spi.InstanceIdGenerator [See nested exception: java.lang.ClassCastException: org.quartz.simpl.SimpleInstanceIdGenerator cannot be cast to org.quartz.spi.InstanceIdGenerator]

As far as I can tell, Wildfly doesn't use quartz (does it?), so I assume there is a classloading confilct with the quartz dependency from the other application.  I tried to add a quartz exclusion in Jboss-deployment-structure, but the conflict persists.  This is my jboss-deployment-structure:

I can't find much in the way of documentation on classloading conflicts between two deployed wars.  Am I doing something wrong here?   Any help would be appreciated.  Thanks.

Quartz - 2.2.1

Wildfly - 9.0.1
